Airport security might not have a sense of humor about this, and it could backfire and make things worse so take this into consideration but you can purchase a pair of privacy underpants that also serves as a radiation shield. The underpants feature a fig leaf over your genitals. When your body is x-rayed security personnel will not be able to see your private parts.
Save yourself some grief and don't wear metallic accessories because you are going to have to remove them before you go through the metal detector. If you have metallic items in your pockets you must remove them too.
If you are carrying on gels or liquids they must be packed in bottles, which must be put in a clear plastic zip lock bag, so they can be seen by security.
While you are standing in line, see what problems those passengers ahead of you are encountering so you know what to avoid doing or saying. Buy and use TSA approved cases for your laptop and other items.
Have your driver's license or passport and your boarding pass at the ready. Do not wake until the last minute and then start searching through the bowels of your purse trying to locate them. This irritates everyone and, obviously, holds up the line.
